Description

Technical Field

[0001] The present invention relates to the technical field of packaging automated assembly, and in particular to a multifunctional packaging mechanical automated assembly device and a method for using the same. Background Art

[0002] Packaging machinery is a device that packages items. Before packaging items, the production line needs to make preliminary settings for the packaging boxes. The packaging boxes need to be processed from flat cardboard into boxes to facilitate the processing of items.

[0003] For example, Chinese patent 202111447984.4 discloses: a carton folding device, which can form a cooperative extrusion with the forming block of the base by moving the forming block assembly and the folding block assembly, so as to fold the cardboard into a target shape. Since the pressing operation of the forming block assembly and the folding block assembly is relatively simple, compared with the manual folding method, it can save a lot of manpower, improve efficiency, and speed up the carton folding process. In addition, since the folding is achieved by mechanical downward pressure, stable folding can be achieved for thicker cardboard or cardboard with insufficient crease depth, and the folding effect is more stable than the manual method, and will not cause the problem of irregular folding;

[0004] The above-mentioned prior art realizes the locking effect of the packaging box by buckling the upper wing, side wing and lower wing together when packaging the packaging box. Some prior art directly glues the folded part of the packaging box with glue. For example, Chinese patent 202021919993.X discloses: automatic carton folding and gluing machine, which can glue the packaging boxes. However, the packaging boxes using the bonding method do not have the buckling structure of the upper wing, side wing and lower wing, so the strength is limited. Summary of the invention

[0005] The purpose of the present invention is to provide a multifunctional packaging machinery automatic assembly device and a method of using the same. By adopting the buckling structure of the upper wing, side wings and lower wing, the upper wing and the lower wing can be connected for a second time by glue, thereby ensuring the strength of the packaging box. Compared with the direct gluing method and the buckling method, the strength is higher.

[0046] S5. The first telescopic rod drives the lifting block to rise. At this time, the adsorption plate is always attached to the top of the packaging box. The rubber hose first leaves the interior of the packaging box. During the rising process, the vertical rod slides upward inside the vertical tube, so that a negative pressure is formed inside the vertical tube.

The first telescopic rod (203) drives the lifting block (202) to rise. At this time, the suction plate (401) is always attached to the top of the packaging box (3). The rubber supply hose (205) first leaves the interior of the packaging box (3). During the rising process, the vertical rod (409) slides upward inside the vertical tube (405), so that a negative pressure is formed inside the vertical tube (405). Since the interior of the vertical tube (405) is connected to the negative pressure chamber (403) through the through hole (404), a negative pressure is also generated inside the negative pressure chamber (403). At this time, the first telescopic rod (203) drives the lifting block (202) to continue to rise. Under the action of the negative pressure, the suction plate (401) always sucks the upper wing (302), the side wing (301) and the lower wing (303) on the top of the packaging box (3), so that the three can be close together.
